UK: Cemex will supply 40,000t of lining-sprayed concrete for the construction of the 13km central section of the Thames Tideway sewer project in Greater London. Engineering partners Ferrovial Construction and Laing O’Rourke will use the concrete for shafts and launch tunnels. The company produced the concrete at its Buxton, Derbyshire concrete plant. It says that it offers ultra-high strength, consistency and two-hour workability in line with the stringent requirements of the job. It also needs to be pumpable with a pipeline length of up to 400m. The producer will deliver up to 3000t/month of the concrete to Central London over ‘a few months.’

Europe, Middle East, Africa and Asia president Sergio Menendez said “The Thames Tideway Tunnel project is one of incredible scale which will solve serious capacity issues with London’s sewer system and have considerable benefits for the area’s wildlife and population, while also preventing pollution, creating jobs, a rejuvenated river economy and new areas of public space.” He added “This is a remarkable piece of engineering, and we’re proud to be working with world-class contractors to build this key infrastructure in the most sustainable and cost-effective way possible for one of the world’s greatest cities.”

The 25km ‘Super Sewer’ will conduct the city’s sewage to a new treatment facility at Abbey Mills in the Borough of Newham. The central section runs between 30m and 60m below the Thames past part of West London, Westminster and the City of London.
